The switch towards battery technologies like lithium iron phosphate (LFP) is leading to major growth in demand for sulphur and sulphuric acid.

Madhya Bharat Agro Products has announced board approval for a major capacity expansion at its Dhule manufacturing facility. The expansion represents a comprehensive enhancement of the company's fertilizer production capabilities, including 330,000 t/a of diammonium phosphate and NPK fertilizer, a 66,000 t/a phosphoric acid plant, and a 396,000 t/a sulphuric acid plant. The expansion plan is part of a strategy of vertical integration in fertilizer production. The addition of phosphoric acid and sulphuric acid production capabilities will support the primary DAP/NPK manufacturing operations, creating operational synergies and potentially reducing input costs, according to the company.

Süd-Chemie discusses the importance of pressure drop in a sulphuric acid plant and the many benefits that can be gained from using a guard bed, typically in the first bed of the converter to safeguard the catalyst bed and increase campaign life.

Begg Cousland Envirotec reviews different mist eliminator types and some of the operational problems encountered which can be managed by correct installation, targeted cleaning or replacement, and selecting appropriate corrosion-resistant materials.

In this real world case study, Topsoe demonstrates how cost effective catalyst changes can result in significant production increase without any equipment changes or revamps, all while maintaining compliance with emission limits.

Recalibrate™ has developed a next generation sulphur burning plant to produce sulphuric acid with ultra-low sulphur dioxide and zero NOx emissions, designed to derisk the permitting process and increase speed to market for new sulphuric acid plants.

Metso - third part of order related to Almalyk MMC's copper smelter project booked - set to produce 1.8 million tpa of sulfuric acid

Platinum-promoted honeycomb catalyst bricks offer function as total oxidation catalysts that convert all oxidisable species under appropriate temperature and oxygen conditions. P&P Industries presents a case for a H2S-rich gas stream – relevant to the fibre industry, Claus offgas treatment, and other chemical sectors.

Freeport Indonesia may be forced to suspend operations at its Manyar smelter at the end of October due to a lack of copper concentrate, according to local press reports. The news follows the mudslide at the Grasberg mine in September, which killed seven workers. Grasberg, which represents almost 3% of global copper mine production, has halted production and Freeport says that it may not return to pre-accident operating rates until 2027. Stocks of copper concentrate at Grasberg were estimated to be only sufficient to operate the Manyar smelter until the end of October. The $3.7 billion Manyar smelter only resumed operations in May after a fire broke out in October last year, damaging the plant.

Aurubis says that it is in discussions with the US government about possible financial support for the construction of a new copper smelter. Reuters reports comments from Aurubis CEO Toralf Haag during LME Week that there had been a positive response from the Trump administration. The US is currently only able to supply about half of its refined copper demand of 1.7 million t/a from domestic production, and the gap may widen as demand increases.
